TECHNICAL FIELD

The present invention relates to a fitment suitable for use with avariety of a fluid delivery mechanism of cleaning implements used toclean hard surfaces.

The present invention also relates to fluid delivery mechanisms suitablefor a cleaning implement for cleaning a hard surface.

BACKGROUND OF THE INVENTION

The literature is replete with products capable of cleaning hardsurfaces such as ceramic tile floors, hardwood floors, counter tops andthe like. In the context of cleaning floors, numerous mopping devicesand other cleaning implements are described which comprise a handleattached to a mop head, a fluid delivery mechanism which can be eitherattached to or incorporated within the handle and a reservoir which canbe used to store a cleaning composition and which is in fluidcommunication with the fluid delivery mechanism. These cleaningimplements usually have a handle comprising at least one pole segmentattached at one end to a mop head and at the other end to a hand-grip.The hand-grip can include a trigger, a switch or any other type ofactuating mechanism suitable for remotely actuating the fluid deliverymechanism. Some cleaning implements comprise a reservoir which ispermanently attached to the implement and which can be filled by a user.Examples of such cleaning implements are disclosed in U.S. Pat. No.2,228,573 to A. L. Lowe, filed Mar. 4, 1938, and U.S. Pat. No. 6,227,744to Fodrocy et al, filed Oct. 12, 1999, which disclose cleaningimplements with a refillable reservoir. Other types of cleaningimplements comprise a reservoir which is removably attachable to thefluid delivery mechanism of the cleaning implement. One example of suchcleaning implements can be found in International Application serial NoPCT/US01/09498 to Hall et al, filed Mar. 23, 2001, and assigned to theClorox Company, which describe cleaning implements having a liquidreservoir which is removably attachable to a fluid delivery mechanismwhich can be integrated into a cap and which is removably attachable tothe finish of the reservoir. The first end of a tube is attached to thiscap and the second end is attached to a nozzle which can be removablyattached to the mop head of a cleaning implement. In order to replace anemptied reservoir, a user must remove the nozzle from the mop head, thenthread it through the universal joint connecting the mop head to thehandle and remove the cap from the emptied bottle. A user can thenreattach the cap to a new filled reservoir and then reattach the nozzleto the mop head. Alternatively, when replacing an emptied reservoir, theuser can also leave the nozzle attached to the mop head but in thiscase, the length of the tube can limit the ability of the user tomaneuver or manipulate the reservoir while maintaining the cleaningimplement stable. In addition, the disclosed fitment including the fluiddelivery mechanism is specific in the sense that it is only usable as agravity fed delivery mechanism and does not allow the user to use thereservoir with another kind of fluid delivery mechanism.

Another example of such a cleaning implement is disclosed in copendingU.S. patent application Ser. No. 09/831,480, to Policicchio et al.,filed Nov. 9, 1999, and assigned to the Procter & Gamble Company. Thereservoir of the described cleaning implements can be removably attachedto a fluid delivery mechanism with a mechanism such as the one describedin U.S. Pat. No. 6,206,058 to Nagel et al, filed Nov. 9, 1998, andassigned to The Procter & Gamble Company, which discloses a fitmentremovably attachable to a reservoir and including a venting valve and afluid transfer check valve.

Another type of mechanism is also disclosed in U.S. Pat. No. 6,386,392,to Lawson et al., filed May 22, 2000, and assigned to The Procter andGamble Company, which discloses a reservoir comprising a cap having anopening covered with a needle-pierceable membrane. When this bottle isinserted in the housing of a cleaning implement, this membrane can bepierced by a first needle for delivering a liquid and by a second needlefor venting this reservoir. As the cap having the needle-pierceaclemembrane is attached to the reservoir, the user can conveniently handlethe reservoir and insert it or remove it from the housing. Nonetheless,this type of reservoir can only be used with a fluid delivery mechanismcomprising at least one needle.

While the prior art addresses the problem associated with cleaningimplements having a liquid delivery mechanism to deliver a liquid from areservoir, the fitments which are disclosed are specialized in the sensethat they do not provide a fluid transfer fitment usable with a varietyof fluid delivery mechanisms which can be conveniently attachable by auser to a reservoir.

As such, there remains a need for such a fitment attachable to areservoir that offers both convenience, a low manufacturing cost and theability to be used with a variety of fluid delivery mechanism.

DETAILED DESCRIPTION OF THE INVENTION

While not intending to limit the utility of the fluid delivery mechanismherein, it is believed that a brief description of its use inassociation with a modern mopping implement will help elucidate theinvention.

In heretofore conventional wet-mopping operations, the mop user requiresa source of detersive liquid for application to the surface beingcleaned by means of the mop head. Earlier practice was to dip the mophead into an external source of liquid, such as a bucket, optionallywring-out the excess of liquid, and then apply the mop head to thesurface with sufficient force to dislodge soil therefrom. Unfortunately,after repeated usage, the mop heads themselves, become dirty,unsanitary, unsightly and have to be removed and laundered.

Modern mopping implements employ disposable sheets or absorbent pads,which are releasably affixed to the head of the mopping implement, andwhich can conveniently be discarded and replaced after soiling. Evenmore modern implements carry their own reservoir of detersive liquid,thereby greatly enhancing their usefulness and convenience. In use, theliquid is dispensed onto the surface being cleaned via a liquid deliverymechanism.

As will be immediately appreciated, it becomes necessary to, somehow,affix the reservoir to such an implement. Moreover, from time-to-time,it is necessary to replenish the detersive liquid in the reservoir. Aswill be seen from the disclosures herein thisaffixing-usage-removal-refill-replacement sequence results in severalproblems whose solutions are non-trivial.

The first problem faced by the manufacturer is that the reservoir istypically inverted and affixed to the implement in an inverted positionso that the gravity force contributes to the deliver of the detersiveliquid. Inversion of a fluid-containing reservoir can, of course, resultin spillage. Moreover, with certain designs, a small amount of liquidcan remain in the reservoir and/or in the implement and/or in thevarious fitments and tubes connecting the whole assembly when the liquidin the reservoir is sufficiently depleted that its refill is judgednecessary or that a different type of detersive liquid is desired. Evensuch small amounts of liquid can cause unacceptable spillage or leakagewhen the reservoir is removed.

In addition, the coupling of the inverted reservoir to the implementmust be simple for users so that an essentially leak-proof joint orconnection is achieved. Moreover, various vents, seals, valves, and thelike, must be employed to provide good flow of the detersive liquid tothe mop head or directly onto the surface being cleaned. Operationalmeans to start-and-stop the liquid flow must be provided. Yet, theoverall construction of the implement and its reservoir should besufficiently simple that it is economical to manufacture and sell. Asnoted, the overall construction of the reservoir and its interconnectingfluid transfer fitment, is preferably one that would be useful on avariety of implements having different types of fluid deliverymechanism.

The foregoing considerations are addressed by the present invention, aswill be clear from the detailed disclosures which follow.

Reference will now be made in detail to the present preferredembodiments of the invention, examples of which are illustrated in theaccompanying drawings wherein like numerals indicate the same elementsthroughout the views and wherein reference numerals having the same lasttwo digits (e.g., 20 and 120) connote similar elements.

I. Fluid Transfer Fitment

Referring to FIG. 1, a fluid transfer fitment which is preferablyremovably attachable to a reservoir is represented.

In one embodiment, the fluid transfer fitment 10 comprises a cap portion20 having an engaging segment 120 with an opening 220 as shown in FIG.2. In one embodiment, the cap portion 20 and the engaging segment 120can be made of any kind of plastic materials, metals or any combinationthereof. In a preferred embodiment, the cap portion 20 and the engagingsegment 120 are made of Copolymer Polypropylene. In one embodiment, thecap portion 20 can be attached to a reservoir (not shown for clarity)but it can be preferred that the cap portion 20 be removably attachableto the finish of a reservoir. In one embodiment, the reservoir can havea base portion connected to a wall portion forming a cavity and a“crown” or top portion which is connected to the wall of the reservoirand which can have a finish portion for receiving the fitment 10. Thecap portion 20 can be removably attached to a reservoir with screwthreads 320 located on the inner surface of the cap portion, as it iswell know in the art, but the cap portion can also be removably attachedto a reservoir via a clip member, a bayonet portion or with a plug sealand still provide the same benefits. In one embodiment, the engagingsegment 120 can have a substantially cylindrical shape and a heightcomprised between about 5 mm and 30 mm, an inner diameter comprisedbetween about 5 mm and about 60 mm and an outer diameter comprisedbetween about 6 mm and about 65 mm. In a preferred embodiment, theengaging segment 120 can engage a receiving member of a fluid deliverymechanism which will be later described. One skilled in the art willunderstand that the engaging segment 120 can have any other shape andstill provide the same benefits. Non-limiting examples of suitablecross-sectional shapes can be triangular, rectangular or, moregenerally, polygonal but it can be preferred that the engaging segmenthave substantially the same cross-sectional geometric shape as thereceiving member. The fluid transfer fitment 10 can comprise aninterconnecting member 30, as shown in FIG. 2-4, which can be locatedwithin the cap portion 20. For ease of manufacturing, the cap portionand the interconnecting member 30 can be two distinct elements but oneskilled will understand that these elements can be manufactured as asingle element via a molding process. The interconnecting member 30 canhave a fluid transfer opening 130 and a vent opening 230. In oneembodiment, a vent valve 40 can be in fluid communication with the ventopening 230 of the interconnecting member 30 via a tube 50 attached in asubstantially leak-tight manner to the vent valve 40 and the ventopening 230 such that air from the outside atmosphere can penetrate inthe reservoir to compensate the “void” left by the liquid beingwithdrawn from the reservoir while substantially preventing the liquidin the reservoir from flowing through the vent opening 230. The ventvalve can be any known vent valve in the art such as for example,duckbill valve, ball and spring valve, slit valve or a venting membranecomprising a porous materials which allows air transport in onedirection but no liquid transport in the opposite direction. In oneembodiment, the vent valve 40 can be attached to the end of a tube 50such that when the fluid transfer fitment is attached to a reservoirfilled with a fluid, preferably a liquid, the vent valve 40 is locatedwithin the reservoir, in a region substantially adjacent the bottom wallof a reservoir. Among other benefits, the location of the vent valve 40in a region a region substantially adjacent the bottom wall of thereservoir, minimizes the risk of leakage of the liquid through the checkvalve 40 when the reservoir is inverted. In one embodiment, the ventvalve 40 can be a normally opened type of vent valve which stayssubstantially opened until it is submersed in a fluid and the pressureof the fluid onto the walls of the valve causes this valve to close.When the normally opened valve is submersed in for example a liquid, airis allowed to flow through the normally opened valve when the pressuredifferential which is caused by the liquid being withdrawn from thereservoir, forces the vent valve to open and then, to reclose when thepressure is equalized. In another embodiment, the vent valve 40 can be anormally closed type of vent valve, which stays substantially closedeven when it is not being submersed in a fluid. When the normally closedvalve is submersed in for example a liquid, air is allowed to flowthrough the normally closed valve when the pressure differential whichis caused by the liquid being withdrawn from the reservoir, forces thevent valve to open or “crack” and then, to reclose when the pressure isequalized. In a preferred embodiment, the vent valve 40 is a duckbillvalve made of an elastomeric material such as silicones, rubbers, PolyVinyl Chloride, metallocene catalyzed Low Density Polyethylene and thepressure differential between the outside atmosphere and the reservoirand which causes air to flow through the check valve 40 is between about0 bar and about 0.5 bars, preferably between about 0 bar and about 0.2bars. In one embodiment, the vent valve 40 can be located within asubstantially rigid shielding member 140 which protects the check valve40 and reduces the chance that the check valve 40 would accidentallyopen when the fitment 10 is attached to the finish of a fluid filledreservoir. One skilled in the art will understand that a vent valve 40in fluid communication with a vent opening may only be required when thereservoir needs to be vented. This might be the case for example, with areservoir having substantially rigid walls, i.e. walls which do notdeform sufficiently to compensate the negative pressure created in thereservoir when the fluid is withdrawn from the reservoir. In oneembodiment, the reservoir can be made of a substantially flexiblematerial such as a flexible pouch or sachet, which can deform as theliquid is withdrawn from the reservoir. In another embodiment, thereservoir can have substantially non-deformable walls and asubstantially flexible pouch for storing a liquid and being locatedwithin the reservoir. As the fluid is withdrawn from the pouch, thepouch is deformed and no venting is necessary. In yet anotherembodiment, a reservoir having substantially rigid walls can have a ventopening, located for example on the bottom surface of the reservoir.This vent opening can be sealed with a one way valves like an umbrellavalve, a ball valve or any of the previously discussed vent valves orwith a piece of adhesive tape such that the fluid contained in thisreservoir does not leak through this vent opening when the reservoir isin a upright position. The reservoir can also have instructionsinstructing the user to remove this adhesive tape when the bottle isinverted and/or connected to the fluid delivery mechanism of a cleaningimplement. In another embodiment, a user can also be instructed topuncture a wall of the reservoir, preferably the base portion of thereservoir, when the reservoir is inverted and/or fluidically connectedto the fluid delivery mechanism.

In one embodiment, the cap portion 20 can have an opening 420 forallowing the vent opening 230 to be in fluid communication with theoutside atmosphere. In a preferred embodiment, the cap portion 20 canhave a groove 520, preferably a substantially circular groove, locatedon the inner bottom surface of the cap portion as shown in FIGS. 3 and4, such that no matter where the vent opening 230 is located relative tothe opening 420 of the cap portion, the vent opening is always in fluidcommunication with the opening 420 of the cap portion 20. A first sealmember 60 which can be for example an O-ring allows the interconnectingmember 30 to be connected to the cap portion 20 in a substantiallyleak-tight manner. A second seal member 70, which can have asubstantially annular shape prevents the fluid from flowing through thevent opening 230 of the cap portion when the fitment 10 is attached to areservoir and the reservoir is inverted. The first and the second sealmembers 60 and 70 can be made of Polyethylene, Polypropylene, Poly VinylChloride, rubbers, silicones, a laminate with foamed Polyethylene orPolypropylene, Ethylene Vinyl Acetate, Ethylene Vinyl Alcohol Aluminiumor any kind of elastomeric materials. The skilled artisan willunderstand that the first and second seal members 60, 70 may not berequired when the cap portion 20 and the interconnecting member 30 aremolded as a single element. In one embodiment, the fitment 10 can have acheck valve 80 for controlling the flow of fluid being withdrawn fromthe reservoir. The check valve 80 can have an actuating shaft portion180 having a first end and a second end. The actuating shaft portion 180is distally movable within the engaging segment 120 and/or theinterconnecting member 30. In a preferred embodiment, the actuatingshaft portion 180 can have a substantially cross shape and it can havefour fins 1180 slideably movable within the opening 130 of theinterconnecting member 30. Without intending to be bound by any theory,it is believed that the fins 1180 act as a guiding means for the checkvalve 80. The actuating shaft portion 180 can be connected to a pistonportion 280 which can have the complementary shape of the opening 220 ofthe cap portion 20 or the complementary shape of the fluid transferopening 130 of the interconnecting member 30. This piston portion 280prevents a fluid from flowing through the opening 220 of the cap portionand/or the fluid transfer opening 130 of the interconnecting member 30as shown in FIG. 3. In one embodiment, the actuating shaft portion 180and the piston portion 280 can be made of any type of plastic materials,metals or combinations thereof. In a preferred embodiment, the actuatingshaft portion 180 and the piston portion 280 are made ofPolyoxymethylene. In a preferred embodiment, the piston portion 280 canhave a seal member 1280 which can be an O-ring, and which can seal theopening(s) 220 and/or 130 in a substantially leak-tight manner. In apreferred embodiment, the check valve 80 can be spring-loaded with aspring member 380 which can resiliently maintain the opening(s) 220and/or 130 closed until enough pressure is applied on the check valve 80to move the piston portion 280 distally such that a fluid can flowthrough the openings 220 and 130 as represented in FIG. 4. In apreferred embodiment represented in FIGS. 3 and 4, the check valve 80 iscapable of closing the opening 220 of the cap portion 20 which islocated in a lower region of the engaging segment 120. In thisembodiment, the diameter of the opening 220 is preferably smaller thanthe diameter of the adjacent inner cylindrical volume of the engagingsegment 120 such that the fluid can flow along the actuating shaftportion 180 and around the piston portion 280 and seal member 1280 andthen through the opening 220 when the check valve 80 is displaced withinthe engaging segment 120 as shown in FIG. 4. A user can easily andconveniently attach the previously described fitment to the finish of afluid filled reservoir and then manipulate this reservoir without havingthe fluid leak through the opening 220 as the spring-loaded check valvekeeps this opening closed. Among other benefits, the previouslydescribed fitment minimizes the risk of spillage of a liquid which inone embodiment can be a cleaning solution having at least an activeingredient. A user can also connect the filled reservoir with thefitment to any fluid delivery mechanism which can be used tocontrollably or permanently apply pressure on the check valve such thatthe fluid contained in the reservoir flows by gravity from the reservoirwhen the reservoir is inverted, i.e. when the fitment is substantiallypointing downward.

In another embodiment, the check valve 80 can be a movable spring-loadedball valve or a slit seal valve which can be engaged by a probe.

In another embodiment, the fitment 10 can be attached to the finish ofthe “crown” portion of a reservoir and an additional cap portion can beattached to the base portion of the reservoir such that a user canrefill the reservoir through the additional cap when the reservoir isinverted.

One skilled in the art will understand that the previously describedfitment can be used with any fluid delivery mechanism having a receivingmember.

II. Fluid Delivery Mechanism.

Another aspect of the invention is related to fluid delivery mechanismsand in particular cleaning implements having a fluid delivery mechanismcomprising a receiving member, which can be used in combination with thepreviously described fluid transfer fitment.

Referring to FIG. 5, a cleaning implement 5 having a fluid deliverymechanism is represented. In one embodiment, the cleaning implement 5comprises a handle 15, rotatably attached at one end to a mop head 25suitable for retaining an absorbent cleaning pad or cleaning sheet (notshown for clarity) and at the other end to a pistol-grip 35 comprising atrigger member 135. The handle of the cleaning implement can have asingle pole segment but preferably comprises a plurality of polesegments 115 which can be releasably attached to each other. A suitablelocking mechanism for permanently or releasably attach two consecutivepole segments is described in copending U.S. application Ser. No.60/409,261 to Hofte et al., filed Sep. 9, 2002 and assigned to TheProcter and Gamble Company.

In one embodiment, the cleaning implement comprises a housing 45 forenclosing a fluid delivery mechanism and receiving at least a portion ofa reservoir 55 and which is attached to the handle 15.

FIG. 6 shows the lower portion of the handle 15 which can be rotatablyattached to the mop head 25 via a universal joint 65 having tworotational axes. In one embodiment, the handle 15 is attached to the topsurface of the mop head via a universal joint 65 having a first and asecond rotational axis X-X and Y-Y where the first rotational axis X-Xis substantially perpendicular to the second rotational axis Y-Y. In apreferred embodiment the first and second rotational axes of theuniversal joint 65 are located in two different planes as shown in FIG.6. In one embodiment, the mop head comprises at least one but preferablyfour grippers 125 for engaging and retaining an absorbent cleaning pador a cleaning sheet about the mop head 25. A non-limiting example ofsuitable grippers can be found in copending U.S. patent application Ser.No. 10/216,117 to Kingry et al., filed Aug. 9, 2002, and assigned to TheProcter and Gamble Company. In another embodiment, hook fasteners can beattached to the mop head 25, preferably to the lower surface of the mophead, for engaging corresponding loop fasteners, which can be located onan absorbent cleaning pad or cleaning sheet, preferably to the topsurface of a cleaning pad or cleaning sheet. In a preferred embodiment,a nozzle 225 is attached to the top surface of the mop head 25 and issubstantially adjacent to the leading edge of the mop head 25. In oneembodiment, the cleaning implement comprises at least one nozzle 225which can be fixedly or releasably attached to the mop head 25. Oneskilled in the art will understand that the nozzle 225 can also beattached to the universal joint 65 or the handle 15 and still providethe same benefits. The nozzle 225 can be any nozzle known in the art,which is suitable for generating at least one stream of fluid. In oneembodiment, the nozzle 225 is capable of generating at least one,preferably between 1 and 10, continuous streams of fluid. In anotherembodiment, the nozzle 225 is capable of generating at least onediscontinuous stream of fluid. In one embodiment represented in FIG. 7,the nozzle (not shown) can be in fluid communication with the fluiddelivery mechanism 12 located in the housing 45 via a tube 75. The tube75 can be made of any type of material suitable for conveying a fluid ina substantially leak-tight manner. Non limiting examples of materialsuitable for the tube can be Polyurethane, Poly Vinyl Chloride,Polyethylene, Polypropylene, metallocene catalyzed resins or anymixtures thereof. In a preferred embodiment, the tube 75 can be insertedthrough an opening 215 located radially in the handle 15. This opening215 is preferably located in a portion of the handle 15 which is atleast partially covered by the housing 45 and then the tube 75 runsalong the handle 15 towards the mop head 25. In one embodiment, the tube75 can extend or exit from a lower portion of the handle 15 through anopening located radially on a portion of the handle 15, preferablylocated adjacent the mop head 25. In a preferred embodiment, representedin FIG. 8A the tube 75 extends from the distal end of the handle 15 andpasses within the universal joint 65. Among other benefits, the locationof the tube 75 within the handle 15 and preferably within the universaljoint 65, prevents the tube from getting entangled with the handle 15when the user is cleaning a hard surface such a floor. The location ofthe tube 75 within the handle 15 and preferably within the universaljoint 65 also minimizes the risk of the tube being damaged during use,transport, packaging and/or storage of the implement. In one embodiment,the tube 75 can be located outside the handle 15. In this embodiment,the tube 75 can be located within the universal joint 65 oralternatively can go around the universal joint 65 and the handle 15.

Optionally but preferably, at least one resilient member 85 can belocated about the portion of the tube 75 which is located within theuniversal joint 65 as shown in FIG. 8A. Without intending to be bound byany theory, it is believed that when the handle 15 is moved at anextreme angle relative to the mop head 25, i.e. when the handle issubstantially parallel to the top surface of the mop head 25, the tube75 can be pinched. Depending on the mechanical properties of thematerial used to manufacture the tube 75 (such as elasticity or recoveryproperties), the pinching of the tube 75 can result potentially in apermanent deformation of the tube 75 which, in turn, can impact on theflow rate of a fluid flowing within the tube 75 as well as the spraypattern generated by the nozzle 225 of the cleaning implement. Theimpact on the flow rate or spray pattern can be noticeable when thecleaning implement is a gravity fed implement, such as the one whichwill later be described and which uses gravity for conveying the fluidfrom the reservoir to the nozzle 225. A portion of the tube 75 locatedwithin the universal joint can be pinched when the portion of the handlerotatably attached to the mop head is “leaning” substantially againstthe top surface of the mop head 25 as shown in FIG. 8B. This situationcan happen when the cleaning implement is packaged in a box or a cartonto be shipped, stored and displayed in a store. While being capable ofbeing deformed to the same extent that the tube 75, the resilient member85 returns to its original shape when the angle between the handle 15and the mop head 25 is not as acute. The resilient member 85 can be suchthat it substantially restores the shape of the portion of the tubewhich has been pinched, therefore offering less resistance or frictionsto the fluid flowing within the tube 75. In one embodiment, theresilient member 85 can be a spring made of stainless steel and can belocated outside but preferably within the inner portion of the tube 75which is located within the universal joint 65. In another embodiment,the resilient member 85 can be a hollow member having a substantiallycorrugated shape as shown in FIGS. 8C and 8D. This corrugated shapehollow member can be located substantially around or within the portionof the tube located within the universal joint 65. In anotherembodiment, a corrugated shape hollow member can be used to fluidicallyconnect a portion of the tube 75 located above the universal joint 65,to a portion of the tube which is in fluid communication with the nozzle225 or even directly to the nozzle 225. The shape recovery property ofthe resilient member 85 contributes to minimize the frictions andturbulences of the liquid which is flowing down to the nozzle 225 and,as a result, optimizes the flow rate of the liquid and the spray patterngenerated by the nozzle 225.

II. (a) Gravity Fed Fluid Delivery Mechanism.

As previously discussed, the fluid delivery fitment can be attached to afluid filled reservoir, as represented in FIG. 9 and can inverted andthen be connected to a fluid delivery mechanism of a cleaning implementhaving a receiving member.

For clarity purposes, FIG. 10 shows a portion of the handle of thecleaning implement having a housing 45 into which at least a portion ofa fluid filled reservoir 55 is inserted. In one embodiment, the housing45 forms a cavity, as shown in FIG. 7, where the functional elements ofthe fluid delivery mechanism 12 are preferably located and which allowsa user to insert at least a portion of a reservoir 55. One skilled inthe art will understand that for a cleaning implement having a gravityfed fluid delivery mechanism, it can be preferred that the fluid filledreservoir and the fluid delivery fitment as shown in FIG. 9, be insertedin the housing 45 such that the fitment, which is attached to thereservoir 55, points in a substantially downward direction.

In one embodiment, a docking member 95, represented in FIG. 11, can beattached to the housing and/or the handle of the cleaning implement viascrews, rivets, clips, adhesive or any molding or welding process as itis known in the art. In a one embodiment, the docking member 95 can bemade of any type of plastic material, metals or any combination thereof.In a preferred embodiment, the docking member 95 is made ofAcrylonitrile-Butadiene-Styrene polymer. In a preferred embodiment, thedocking member 95 comprises a cylindrical portion 195 for connecting andattaching the docking member 95 to the handle of the cleaning implement.In one embodiment, the docking member 95 comprises a top surface 295having an upper opening 1295, a wall 395 extending downwardly from thetop surface 295 and forming a cavity 495 for receiving at least aportion of the fluid delivery fitment previously described and a bottomsurface 595 connected to the wall 395 and having a lower opening 1595.In a preferred embodiment, the upper and lower openings, 1295 and 1595,are substantially circular. In one embodiment, the diameter of the upperopening 1295 is greater than the diameter of the lower opening 1595. Ina preferred embodiment, the diameter of the upper opening is slightlygreater than the diameter of the cap portion 20 of the fluid deliveryfitment 10 and the diameter of the lower opening 1595 is slightlygreater than the diameter of the engaging segment 120 of the fluiddelivery fitment 10 such that the cap portion and the engaging segmentof the fluid delivery fitment 10 fit within the cavity 495 of thedocking member 95 and such that the engaging segment 120 can extendthrough the lower opening 1595.

When the cap portion 120 ofthe fluid delivery fitment 10 is located within the cavity 495 of thedocking member 95 and past the snapping members 695, 795, each snappingmember 695, 795 returns suddenly to its original position and generatean audible signal. Among other benefits, the snapping members 695 and795 provide an audible signal informing the user that the reservoir hasbeen properly inserted in the housing. The snapping members 695 and 795also act as a snapping/locking device maintaining the fitment in placein the cavity 495 of the docking member 95 and therefore the reservoirwithin the housing of the cleaning implement. The reservoir 55 isproperly maintained within the housing until a sufficient pulling orextracting force is applied by the user on the reservoir in order todisengage the reservoir from the housing 45.

For clarity purposes, FIG. 12 shows the housing 45 attached to thehandle 15, a fluid delivery mechanism 12 connected to the docking member95 as well as the fluid delivery fitment 10 connected to the reservoir55 and which is in communication with the fluid delivery mechanism 12.

In one embodiment, the fluid delivery mechanism 12 can be controllablyactuated by a lever member 22 which comprises a first end 122 and asecond end 222. In a preferred embodiment, the first end 122 of thelever member 22 is pivotably connected via a pin or protrusion to anon-moving part of the cleaning implement. In one embodiment, the firstend 122 of the lever member 22 is pivotably connected to the housing 45.In a preferred embodiment, the first end of the lever member 22 ispivotably connected to an extending portion 895 of the docking member 95via an opening 1895 shown in FIG. 11. In one embodiment, the second end222 of the lever member 22 is connected to a longitudinal member 32 suchthat an upward motion of the longitudinal member 32 causes the levermember 22 to pivot about the pivot point 1122 and to actuate the fluiddelivery mechanism 12. The longitudinal member 32 can be any apparatusor device capable of applying a pulling force to the lever member 22such as to cause the rotation of the lever member 22 about the pivotpoint 1122. The longitudinal member 32 is connected to an actuationmechanism which can be a trigger member 135 (shown in FIG. 5) which canbe located about the upper portion of the handle 15, preferably in thehand-grip 35, such that a user can controllably actuate the fluiddelivery mechanism 12 via the longitudinal member 32 and the levermember 22. In one embodiment, the longitudinal member 32 can be a rodmade of a substantially rigid material. In another embodiment, thelongitudinal member can be a cable, a rope, a wire or a tape. In apreferred embodiment, the longitudinal member 32 is a tape which can beput under tension by a self-tensioning mechanism such as the onedisclosed in copending U.S. patent application 60/409,261 to Hofte etal., filed Sep. 9, 2002 and assigned to The Procter and Gamble Company.When this tape is tensioned, a user can controllably pull on the tape,which is windably connected to a spring-loaded winding member, bysqueezing a trigger member.

FIG. 13 shows the lever member 22 pivotably attached to the extendingportion 895 of the docking member 95 with the fluid delivery mechanism12 and a portion of the reservoir 55 covered by the housing (not shownfor clarity purposes).

In one embodiment, the lever member 22 has a substantially “fork” shapeand comprises a right arm portion 322 and an opposing left arm portion422. In a preferred embodiment, the right and left arm portions 322, 422are pivotably connected to the extending portion 895 of the dockingmember 95. In one embodiment, the right and/or left arm portions 322,422 can have at least one but preferably two ear portions 1322, 1422extending upwardly from the right and/or left arm portion. The earportions are capable of contacting and lifting in a substantially upwarddirection a clipping member 72 of the fluid delivery mechanism 12 whenthe longitudinal member pulls on the lever member 22.

In one embodiment represented in FIGS. 14-16, the fluid deliverymechanism 12 comprises a receiving member 42 for receiving the engagingsegment 120 of the fluid delivery fitment 10. The receiving member 42comprises a wall 142 defining a chamber 242 for conveying a fluid fromthe engaging segment 120 of the fitment to the tube 75 in asubstantially leak tight manner. The receiving member 42 comprises anupper inlet 1242 and a lower outlet 2242. In one embodiment, thereceiving member 42 can have a substantially cup shape. In oneembodiment, the engaging member 42 is made of a material which issubstantially deformable and optionally but preferably elastic, i.e.which can be deformed when pressure is applied but returns to isoriginal shape when pressure ceases to be applied against the receivingmember 42. Non-limiting examples of suitable materials havingappropriate deformability, elasticity and recovery properties includenatural and synthetic rubbers, elastomeric materials and silicone typematerials. In a preferred embodiment, the receiving member is made ofsilicone having a hardness or durometry between about 40 degrees Shore Aand 90 degrees Shore A, preferably comprised between about 60 degreesShore A and 80 degrees Shore A. A suitable receiving member is made ofis made by Hayco Manufacturing Ltd company located in Hong Kong. In oneembodiment, the upper portion of the receiving member 42 can beconnected to the bottom surface 595 of the docking member 95. In apreferred embodiment, the upper portion of the receiving member 42comprises a substantially circular channel 1142 such that an annularportion, which is adjacent to the lower opening 1595 of the bottomsurface 595 of the docking member 95, engages the upper portion of thereceiving member 42 within the channel 1142. In one embodiment, theengaging segment 120 of the fitment 10 can be inserted within thechamber 242 of the receiving member through the upper inlet 1242 in asubstantially leak-tight manner. In a preferred embodiment, thereceiving member 42 comprises a substantially circular “lip” 2142, shownin FIGS. 15-20, extending outwardly from the inner surface of thereceiving member 42 such that the diameter at the tip of the “lip” 2142is slightly smaller than the diameter of the engaging member 120. Amongother benefits, the “lip” 2142 improves the leak-tightness of theconnection between the engaging segment 120 and the receiving member 42when the engaging segment 120 is inserted within the receiving member42. When a user inserts the reservoir 55 with the fitment 10 andtherefore the engaging segment 120 within the chamber 242 of thereceiving member 42, the engaging segment 120 can potentially detach aportion if not all of the receiving member 42 from the bottom surface595 of the docking member 95 if the engaging segment is not properlyaligned with the receiving member 42. In a preferred embodiment, aprotecting member 52 (shown in FIGS. 12 and 17) is disposed on the topof the receiving member 42. The protecting member 52 can have asubstantially annular shape and can be sized such that the outer rim ofthe receiving member 42 is “covered” by the protecting member 52. Theprotecting member 52 minimizes the risk that the receiving member 42 isdetached from the docking member 95 when the engaging segment 120 of thefitment 10 is inserted within the receiving member 42. In oneembodiment, when the receiving member is in a relaxed state as shown inFIG. 17, the receiving member has a height A1 comprised between about 10mm and about 100 mm, a lower outer diameter B1 comprised between about10 mm and about 50 mm, an outlet diameter C comprised between about 1 mmand about 20 mm, a top connecting diameter D comprised between about 10mm and about mm, an inner top diameter E comprised between about 6 mmand about 66 mm, an inner “lip” diameter F comprised between about 5 mmand about 64 mm, a connecting thickness G comprised between about 0.5 mmand about 5 mm, an inner chamber diameter H comprised between about 5 mmand about 49 mm, a body thickness I comprised between about 0.5 mm andabout 5 mm, and a lower radius J1 comprised between about 2 mm and 40mm. In one embodiment, when the receiving member is in a compressedstate as shown in FIG. 18, the receiving member has a height A2comprised between about 50% and 99% of the height A1, a lower outerdiameter B2 comprised between about 101% and about 150% of the lowerouter diameter B1, and a lower radius J2 comprised between about 30% andabout 99% of the lower radius J1.

In one embodiment, the fluid delivery mechanism 12 comprises atransition member 62 for conveying a fluid from the receiving member 42to the tube 75 in a substantially leak-tight manner. The transitionmember 62 comprises a hollow body 162 (shown in FIGS. 19 and 18) havingat east one upper opening 1162 in fluid communication with a loweropening 2162. In one embodiment, the upper opening 1162 can be locatedin the upper portion of the transition member 62 and the lower opening2162 can be located in the lower portion of the transition member 62. Ina preferred embodiment, the upper portion of the transition member 62 islocated within the receiving member 42 and the lower portion of thetransition member 62 extends beyond the lower outlet 2242 of thereceiving member 42 such that the lower portion of the receiving member42 can be connected to the tube 75 in a substantially leak-tight manner.Among other benefits, the transition member 62 allows a liquid in thechamber 242 to flow through the upper opening 1162 of the transitionmember 62, within the transition member 62 and through the lower opening2162, in a substantially leak-tight manner. In a preferred embodiment, aclipping member 72 is attached, preferably forceably attached to thelower portion of the receiving member 42 such that a motion of theclipping member 72 in a substantially upward direction as represented bythe arrow A of FIGS. 16 and 18, causes the transition member 62 to movein a substantially upward direction. In a preferred embodiment, theupper portion of the receiving member 42 is fixedly attached to thebottom surface 595 of the docking member 95 such that an upper motion ofthe clipping member 72 causes the receiving member 42 to be deformed asrepresented by the deformation d shown in FIGS. 16 and 18. Among otherbenefits, the clipping member 72 improves the leak-tightness of theconnection between the lower portion of the receiving member 42 and thetransition member 62. In addition, the clipping member 72 provides agreater contact surface allowing the ear portions 1322, 1422 of thelever member 22 to “lift” in an upward direction the transition member62.

In one embodiment, the transition member 62 comprises means 262 foractuating for actuating the check valve 80 of the fitment 10. Theactuating means 262 can be any device suitable for movably engaging thecheck valve 80. Non-limiting example of means 262 for actuating thecheck valve 80 can be rod, pole, shaft, which can be hollow, tubularand/or solid and which allow a fluid to flow within and/or along themeans for actuating the check valve 80 when this actuating means engagesthe check valve 80. In a preferred embodiment, the actuating means is anactuating rod which has a substantially cross shape at across-sectional. The actuating rod 262 is preferably connected to theupper portion of the transition member 62. When a user controllablycauses the longitudinal member 32 to impart a pulling motion to thelever member 22, the ear portions 1322 and 1422, push the clippingmember 72 in a substantially upward direction. The upward motion of theclipping member 72 causes the transition member 62 and the actuating rod262 to move in a substantially upward direction concurrently. As theactuating rod 262 moves in the substantially upward direction, theactuating rod 262 pushes the piston portion 280 upwards such that thelower opening 220 of the engaging segment 120 ceases to be sealedcausing the fluid contained in the reservoir 55 to flow by gravity fromthe reservoir 55 and the fitment 10, into the chamber 242, from thechamber 242 into the tube 75 via the transition member 62, from the tube75 to the nozzle 225 and from the nozzle 225 to a surface to be cleaned.One skilled in the art will understand that the fluid in the reservoir55 keeps flowing to the nozzle 225 as long as the actuating rod 262actuates the check valve 80, i.e. as long as the longitudinal member 32maintains the lever member 22 in an upward position. When the userallows the longitudinal member 32 to return to its original position,the lever member 22 can pivot back to a downward position causing theclipping member 72, the transition member 62 and, as a result, theactuating rod 262 to return concurrently to their original downwardposition as shown in FIGS. 15 and 17, and the biasing action of thespring member 380 causes the piston portion 280 to seal the loweropening 220 of the fitment 10 which, in turn, prevents the fluid fromflowing to the nozzle 225. One skilled in the art will understand thatdepending on the elastic and/or recovery properties of the flexiblereceiving member, the receiving member 42 returns to its originalposition when pressure ceases to be applied on the clipping member 72.In another embodiment, the receiving member 42 can be such that theelastic and/or recovery properties of the receiving member do not allowthe receiving member 42 to return to its original shape on its own whenpressure ceases to be applied on the clipping member 72. In thisembodiment, it can be preferred to add an additional spring member whichcan be connected at one end to the housing 45 or docking member 95 andat the other end to the receiving member 42 either directly orindirectly via the clipping member 72. The actuating rod 262 can haveany shape suitable for actuating the check valve 80. In one embodiment,the actuating rod 262 can have a substantially cross shape and a heightcomprised between about 1 mm and 40 mm, preferably comprised betweenabout 2 mm and 20 mm. In one embodiment, the distance between the checkvalve 80 and the actuating rod 262 is comprised between about 0 mm andabout 10 mm, preferably between about 1 mm and about 5 mm. Among otherbenefits, a “gap” between the actuating rod 262 and the check valve 80minimizes the risk that the check valve is accidentally actuated by theactuating rod 262 when a user inserts the reservoir 55 within thehousing 45.

Optionally but preferably, the transition member 62 comprises a diskportion 362 for sealing the lower portion of the chamber 242 of thereceiving member 42 in a substantially leak-tight manner.

One skilled in the art will understand that when a user actuates thepreviously described fluid delivery mechanism 12 while a fluid filledreservoir and a fitment 10 are inserted within the housing 45, the fluidflows by gravity to the nozzle 225. When the user ceases to actuate thefluid delivery mechanism 12, a column of fluid is “trapped” within thereceiving member 42 and the tube 75 due to the leak-tightness betweenthe check valve 80 and the lower opening 220 of the engaging segment 120as well as the leak-tightness between the engaging segment 120 and thereceiving member 42. In the event a user wishes to remove the reservoirfrom the housing 45 before the reservoir has been emptied, thisleak-tightness to the outside atmosphere ceases and the column of fluidundesirably flows onto the floor surface. This situation may happen whenfor example the user wishes to use a different type of fluid containedin a different reservoir or wishes to disassemble the cleaning implementto decrease its storage space. As a result, it is believed that it canbe useful to add stoppage means from preventing this column of fluid toflow undesirably onto a surface when the reservoir is removed. In oneembodiment, the stoppage means can be a disk portion 362 which can beconnected to the transition member 62 such that it is located betweenthe actuating rod 262 and the upper opening 1162 of the transitionmember 62. In a preferred embodiment, the diameter of the disk portion362 is slightly greater than the diameter of the portion of thereceiving member 42 which is adjacent to the disk portion 362 such thatthe disk portion 362 contacts the inner surface of the receiving memberin a substantially leak-tight manner. The disk portion 362 separates anupper portion 3242 of the chamber 242 of the receiving member 42 fromthe lower portion 4242 of the chamber 242 in a substantially leak-tightmanner as shown in FIGS. 15 and 17. When a user actuates the liquiddelivery mechanism 12, the deformation d of the receiving member asshown in FIGS. 16 and 18, allows the fluid to flow by gravity around thedisk portion 362 of the transition member 62. When the user ceases toactuate the fluid delivery mechanism 12, the receiving member 42 returnsto its original shape as shown in FIGS. 15 and 17, and the disk portionsealably contacts the inner surface of the receiving member 42 causingthe upper portion 3242 of the chamber 242 to be sealingly separated fromthe lower portion 4242 of the chamber 242. One skilled in the art willunderstand that if a user wishes to remove the reservoir 55 from thehousing 45, the column of fluid contained within the lower portion 4242of the chamber 242 and the tube 75 is “trapped” and does not flowunwontedly onto the floor. Without intending to be bound by any theory,it is believed that when the receiving member 42 is compressed, itdeforms substantially outwardly as represented by element d of FIGS. 16and 18 due to the thickness and the concavity of the receiving member42. In addition, when the engaging segment is inserted within thereceiving member, the substantially rigid wall of the engaging segmentcauses the receiving member to deform outwardly rather than inwardly. Inone embodiment, weaknesses can be added to the receiving member 42 inorder to assure its outward deformation. In one embodiment, theseweaknesses can be in the form of a groove or channel.
